GLOBE HOLDER FOR ILLUMINATING FIXTURES.

Application filed. June 21, 1923.

To all whom it may concern:

Be it known that I, FRANK YoKnL, a citi- Zen of the United States,residing at Avalon, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements in GlobeHolders for Illuminating Fixtures, of which the following is aspecification.

This invention relates to an improved globe or shade holding means forilluminating fixtures. 1

The invention has for its principal ob- I jects to provide a globe orshade clamping means of simple construction designed to effectually holda shade or globe in place and readily operable into and out of globeengaging position, the device being neat appearing and cheaplyconstructed.

The invention is particularly useful for use in connection with thelarge globes of ceiling lights, although in no way confined to such use.

The invention may be readily understood by reference to the accompanyingdrawings in which:

Fig. 1 is a side elevation of the shade or globe holder embodying myinvention, showing a globe therein, part of the globe being broken away;

Fig. 2 is a vertical section through the globe holder, showing the globein place;

Fig. 3 is a similar view, with the globe removed;

Fig. 4c is a detail view of one of the globe engaging members; and

Fig. 5 is a detail view, showing the operating means for one of theglobe engaging members.

In the drawings, A designates the globe or shade holder, B is anornamental canopy that may be interposed between the globe holder andthe ceiling, and C designates the globe or shade.

The shade holder comprises an integral sheet metal body or shell, spunor otherwise worked into shape, having a flat top portion 6, an outwardcurved part 7, a short vertical part 8, and a second outwardly curvedpart 9, the curvature of the latter part being convex, while that of theupper or first curved part is concaved. The lower end of this hollow orshell body is open, to permit of the insertion and removal of the upperend of an illuminating Serial No. 646,795.

globe or shade. The contour of the interior of the shell conforms to itsexterior. In the flat top 6 is an opening 10 through which may pass theend of a pipe or other conduit 11 (as shown in Fig. 2) to support theshell.

Secured to the interior of the shell are a plurality, preferably two,globe engaging members 12 and 13 respectively' Member 12 comprises anintegral body having arms 14 conforming to the inner curvature of theshell and secured to the shell by pins 15 passed theret-hrough.

Formed on the body is a shoulder 1 1 adapted to come against verticalpart 8 of the shell, and below this the body is curved or hook-shaped toreceive the head a of the globe C, the end part 16 of the body beingadapted to project into the restricted neck portion a of the globe. Themember 12 is also arcuately curved in a horizontal plane,

in order to engage the circular head a ofv the globe at all points ofcontact therewith.

Member 13, diametrically opposite member 12, is similar to member 12 tothe ex tent described, and similar reference numerals have been appliedthereto. In order, however, that the hook portion of member 13, whichlike that of member 12 is'out of contact with the curved part 9 of theshell, be less resilient than the hook portion of member 12, the pins 15are disposed nearer the body of member 18, instead of being located atthe ends of the arms 14.

Member 12 is provided with a vertical slot 17. Threaded in a bushing onthe shell is a screw or bolt 18 having aknob 19, by means of which itmay be turned. The inner end of this screw is reduced at 20 to passthrough slot 12, and on the inner end of the screw is a washer 21. Bythis arrangement, the inner end of the screw may turn in the slot andslide therein, but, as the screw is turned, it moves in or out,imparting a similar movement to member 12.

In use, the screw is turned to retract the clamping member 12 until thebead of the globe or shade is inserted. Then the screw is turned in theopposite direction, and edge to take up all play between the globe andclamping members, it should be turned no further. A look nut 22 on thescrew between the knob and the bushing may then be turned to secure thepartsdn this position.

The construction herein described is extremely simple, both inconstruction and op eration. The shell entirely houses the clampingmeans, so that the only visible part thereof is the one operating screwand knob.

Various details in the arrangement and construction of parts are withinthe conten'iplation of my invention.

WVhile I have shown the bushing 23 internally threaded-to cooperate withthe threaded bolt 18, it is within the scope of my invention to form thethreaded portion in a wall of'the shell or to otherwise provide a"threaded portion carried by the shell to co- .actwith the threaded'bolt.

I claim as my invention:

1. A globe holding device comprising a hollow shell open at its lowerend for the 'rece'ptionof the top .of a globe, a [plurality of inwardlyturned hook-like globe engaging members on the interior of the shell,and a screw passing through only one of said members and the shell bymeans of which ithe :glo-be engaging onember .inay be moved intoand outof globe engaging position, said other member being substantially fixedin position.

2. A globe holding device comprising a hollow shell open alt-its lowerend for the reception of the-top; of a globe, a globe engaging :memberhaving a free hook-like globe engaging lower end portion and an upper:portion which is secured to theiinterior of :the shell, .a screwengaglng said member and passiiigthrough the shell by means of which thehook-like portion-maybe moved into .and out of globe engagingandvotherlixed non-adjustable globe engagposition,

ing means within the-shell forcooperation withtsaid first globeengagingmember.

7 3. A globe holding device comprising a hollow shell ope-n at itslowerend for the reception of'the'top of a globe,a globe engaging memberhavmg a free hook-like globe engaging lower end portion and an upperportion which is secured to the inte rior of the shell, said memberhaving a vei'tnally disposed slot therein, a screw liar-- ing one endrotatably and slidably retained in the slot, said screw passing throughthe shell and having a threaded support therein, means on the outer endof the screw for turning it whereby to efieet a movement of the hookportion into and out of relatiwly fixed non-adjustable globe engagingposition, and other globe engaging means within the shell forcooperationwith said first globe engaging member.

4. A globe holding device comprising a hollow shell, open at its lowerend for the reception of the top of a globe, a pair of globe engagingmembers secured within the shell having relatively wide areuale curvedhook-shaped globe engaging parts spaced inwardly from the shell, the twomembers being opposite each other, and a screw connecting with only onemember and passing through the shell by means of which said member maybeadjusted toward and away from the other member, the two members beingsuiiiciently wide to provide ample holding and supporting means for theglobe.

5. A globe holder comprising a hollow bell-shaped shell open at itslower end and having an inwardly curved upper portion and an outwardlycurved lower portion, with a substantially vertical iportion between theinwardly and outwardly curved portions, correspondingly shaped resilientglobe supporting devices secured at their upper ends in the shell andhaving their vertical part falling along the vertical part of the shelland having their outwardly curved r p art received in the outwardlycurved part of the shell but spaced inwardly i'rom said outwardly curvedportion, said ture.
